Pull System
A pull system is a workflow methodology where work is initiated based on actual demand rather than forecasts, commonly used in software development and manufacturing. It operates by having downstream processes signal upstream processes when they are ready for more work, often visualized with tools like Kanban boards. This approach helps limit work-in-progress, reduce waste, and improve flow efficiency by ensuring tasks are pulled only when capacity is available.
Developers should use pull systems in agile or lean environments to manage workflow, prevent bottlenecks, and enhance team productivity by focusing on completing current tasks before starting new ones. It is particularly valuable in continuous delivery pipelines, where it helps balance workloads and maintain sustainable development pace, reducing context switching and improving quality through better focus.
